Matters needing attention when spraying
1. Pay attention to improve the wet expansion performance of the liquid medicine. When spraying pesticides, emulsifiable concentrates and oils have strong adhesion on plants, while water and wettable powders have poor adhesion. In order to improve the efficacy of pesticides, when spraying insecticides, dimethyltetrachloride When using pesticides such as glyphosate and glyphosate, a small amount of neutral washing powder can be added as a spreading agent to improve the wet spreading ability of the agent. In some herbicides, adding an appropriate amount of ammonium sulfate can improve the spreading ability. For example, after adding 0.5% ammonium sulfate to dimethyltetrachloride, the absorption time is reduced from 24 hours to 10 minutes.
2. Attention should be paid to the water quality of the diluted medicinal solution. The hardness, alkalinity and turbidity of the water have a great influence on the efficacy of the medicine. When the calcium salt and magnesium salt in the water are excessive, the stability of the emulsion and suspension prepared by the ionic emulsifier will be destroyed. Some pharmaceuticals lose their efficacy due to being converted into non-water-soluble or insoluble substances. In some saline-alkali areas, the pH of the water is too high, which will cause a neutralization reaction with the pharmaceuticals, resulting in decreased efficacy or failure. Turbid water will reduce the activity of pesticides, and will also accelerate the passivation and failure of herbicides such as glyphosate and paraquat. Therefore, it is advisable to choose clean water with a neutral pH value for the water used for the medicinal solution.
3, to prevent pesticide poisoning. During the spraying process, the droplets often drift with the wind, polluting the skin and respiratory tract of the applicator. Therefore, the applicator should do a good job of safety protection, and cannot spray finely on highly toxic pesticides such as methyl 1605 and methamphetamine. Some pesticides are highly toxic, such as insecticides, insecticide rings, and insecticides. Special attention should be paid when using them in densely populated areas.
4. Pay attention to improve the spray quality. The spray method generally requires uniform distribution of the droplets of the liquid medicine, high coverage, and appropriate amount of the liquid medicine. For example, aphids and mites like to harm the back of plant leaves. When controlling, it is necessary to carry out targeted spraying on the back of the leaves to receive the ideal control effect.
